摘要: 以羟基磷灰石(HAP)粉体为原料,用简便方法制备氟羟基磷灰石(FAP)微球.将HAP粉体在不同pH值的NaOAc缓冲液中充分搅拌,加入NaF并水浴加热,制得氟羟基磷灰石(FAP)微球, 并利用TEM、SEM、XRD、FT-IR对微球的结构、成分进行表征, 研究与探讨了微球形成的机制.研究结果表明可以通过改变缓冲液的pH值来控制FAP微球结构.

Abstract: The purpose of this paper was to prepare fluorapatite microspheres with hydroxyapatite powers by simple methods.FAP microspheres were prepared by adding NaF into HAP suspension which was produced by dipped HAP powders into acetic acid-solution, and the suspension was stirred thoroughly and heated in water bath.The formation mechanism, structure and chemical constituent of the microspheres were investigated through various characterization including TEM, SEM, XRD and FT-IR.The results show that the morphology and structure of FAP microspheres could be controlled by change the pH value of acetic acid-solution.
